Hello!I just bought a redline last Monday so I thought I would sign up for the forum and help/get help as much I can. Well, I took the car to get an alarm put on it at Audio Express. They had the car for 7 hours, called me and said its done. I got there and he said I would have to come back the next day cause the installer unplugged my ECM before diconnecting the battery and the car through a check engine light, and airbag light. He said he has a machine to take care of this and it will take 10 minutes. My car only had 120 miles on it at this time. I left the parking lot, went into second, was wanting to pass someone, hit the gas at about 3500rpm still in second, and it seemed like right when I hit boost, this sound came from the engine that just didnt sound healthy. It sounded like high voltage electricity, or like you were taking off in 3rd gear, you know how you get that knock? I know knock comes with gas, and I dont know what kind of gas is in it since the dealer filled it. So I took the car back, they couldnt fix it, said I had to take it Saturn. Took it there, they said my ECM was blown. They took it out, put a new one in, fixed the engine light but not the airbag light. SO venture to say, they are going to have my car till Tuesday because they have no idea what caused this. It just pisses me off because I have yet to have the car a full day! Sorry for the long message, I just had to vent with some people that would understand what Im going through. Well, I cant wait to get to know some people on here! Talk to you later!
